Mode

RAS Secure Client Gateway can operate in one of the following modes:

• Normal Mode: RAS Secure Client Gateway receives user connection requests and checks with RAS Publishing Agent if the user making the request is allowed access. Gateways operating in this mode can support a larger number of requests and can be used to improve redundancy.
• Forwarding Mode: RAS Secure Client Gateway forwards user connection requests to a preconfigured Gateway. Gateways in forwarding mode are useful if cascading firewalls are in use, to separate WAN connections from LAN connections and make it possible to disconnect WAN segments in the event of issues without disrupting the LAN.

Note: To configure the forwarding mode, the RAS Site must have more than one RAS Secure Client Gateway installed.

To use Site default settings, click the Inherit Defaults option. To specify your own settings, clear the option.

Setting the normal mode

To set the normal mode, in the Gateway mode drop-down list, select Normal.

The Preferred Publishing Agent drop-down list allows you to specify a RAS Publishing Agent that the gateway will connect to. This is helpful when Site components are installed in multiple physical locations communicating through WAN. You can decrease network traffic by specifying a more appropriate Publishing Agent. For the gateway to select a Publishing Agent automatically, select the Automatic option.

The Forward requests to HTTP Server option allows you to forward requests that do not belong to RAS Secure Client Gateways (gateways handle HTML5 traffic, Wyse, and URL scheme). To specify multiple servers, separate them with a semicolon. An HTTP server can be specified using an IPv6 address if necessary. Please note that the HTTP server must support the same IP version as the browser making the request.

Setting the forwarding mode

To configure the forwarding mode, in the Gateway mode drop-down list, select Forwarding and specify one or more Gateways. A gateway in forwarding mode will forward all the user connection requests to a pre-configured gateway. Gateways in forward mode are useful if cascading firewalls are in use, to separate WAN connections from LAN connections and make it possible to disconnect WAN segments in the event of issues without disrupting the LAN.
